abstract
There has been an increasing trend towards digital representation of physical assets such as simulating design prototypes, layout infrastructures and process dynamics. We term such representations digital assets and present a design-for-maintenance framework for such assets. A shift in the maintenance strategy of digital assets is essential due to the nature of these assets. Maintenance of digital asset involves preserving all the features of the asset in the midst of computer hardware and software changes. The key is to design self-maintaining and self-preserving digital assets that are platform independent and are easy to use locally as well as in a network environment. The network programming language Java is used to illustrate our design-for-maintenance framework. A comparison is made between physical and digital asset maintenance characteristics and issues. Our framework is compared with existing frameworks, such as Standards for the Exchange of Product Model Data (STEP).
